Oil in exhaust? Normally this will create blue smoke. Sounds more like a busted up head gasket or possible intake gasket, creating white smoke from being ignited in the engine then passing this fog/steam out the exhaust, this moisture is then collecting on the internal sides of the exhaust system basically steam cleaning the pipes ans the end result is black or dark fluid exiting the pipes, This is not good for your Catalytic converter BTY. The smell is anti-freeze.
